Simple solar battery charger
Told a guy I'd do some research for him into a small simple solar system
for use in maintaining the charge on a 12 volt automotive battery. Found this at Harbor Freight: http://www.harborfreight.com/cpi/cta...emnumber=96418 It's a 12 volt, 15 watt panel for cheap ($70). I'm thinking that all he needs to do is wire it up to his battery to trickle-charge it. I think I'd add a diode (IN200x) in series for protection. So will this work? Since they don't list the output voltage for the panel, except to say "12 volts" in the description, I guess one could opt for this larger one: http://www.harborfreight.com/cpi/cta...emnumber=40085 (20 watt panel, made for charging auto & RV batteries, $190) which says it maintains a charging voltage of 17.5 volts, which seems a little high: perhaps a string of 3 or 4 diodes in series would drop the voltage just enough to bring it down to the recommended 13.6 volts or so. -- Personally, I like Vista, but I probably won't use it. I like it because it generates considerable business for me in consulting and upgrades. As long as there is hardware and software out there that doesn't work, I stay in business. Incidentally, my company motto is "If this stuff worked, you wouldn't need me". - lifted from sci.electronics.repair |
